Now that Maxim Integrated MAX3355 'extcon' driver and device tree bindings are upstream along with the 'extcon' hook in the Renesas USBHS driver, we can add MAX3355 device node to the Porter device tree and properly refer to it from the USBHS node instead of using "renesas,enable-gpio" property which only allowed checking the USB ID pin at the driver probe time; now this pin's state can be monitored dynamically!
